''Bombax ceiba'', like other trees of the genus ''Bombax'', is commonly known as cotton tree. More specifically, it is sometimes known as red silk-cotton; red cotton tree; or ambiguously as silk-cotton or kapok, both of which may also refer to ''Ceiba pentandra''. This Asian tropical tree has a straight tall tree and its leaves are deciduous in winter. Red flowers with 5 petals appear in the spring before the new foliage. It produces a capsule which, when ripe, contains white fibres like cotton. Its trunk bears spikes to deter attacks by animals. Although its stout trunk suggests that it is useful for timber, its wood is too soft to be very useful. The dry cores of the ''Bombax ceiba'' flower ((タイ語:งิ้ว))〔(Thai Plant Names )〕 are an essential ingredient of the nam ngiao spicy noodle soup of the cuisine of Shan State and Northern Thailand,〔(Cooking Northern Thai Food – Khanom Jeen Nam Ngeow )〕 as well as the kaeng khae curry.〔(Kaeng Khae Kai (Katurai Chilli Soup with Chicken) )〕 ==Description== ''Bombax ceiba'' grows to an average of 20 meters, with old trees up to 60 meters in wet tropical regions.
